Title: Improvements in or relating to gramophones or the like
IPC: G11B3/46
Filed: 1924-03-21
Abstract: 236,983. Forse, L., Bradford, F. G., and Paynter, J. B. March 21, 1924. Tool-arms and mountings. - A gramophone needle-feed comprises a rotatable disc-shaped magazine 19 in which the needles are disposed radially in grooves 20 or in concentric perforated bands, said magazine being pivoted in a circular casing 1 parallel to the diaphragm. The magazine is caused to revolve by moving a spring- returned lever 7, a spring pawl 3 on which engages a ratchet-wheel 2 on the magazine, stops 4<1>, 4<2> being provided to limit the movement to that required to bring a new needle in position. The lever 7 has an extension 8 which supports a small hinged tray 9 which comes under the needle carrier 15 to stop the needle as it falls from the magazine, and a cam surface 10 to release a spring-pressed needle-clamping bar 11. In operation, when the lever 7 is moved the camsurface 10 releases the lever 11 so that the old needle drops before the tray 9 comes beneath the needle holder, the disc 19 is moved at the same time and a new needle drops on to the tray through a passage 18. As the lever returns, the needle 14 strikes an extension 9<1> of the tray, causing it to swing over to a horizontal position so that the needle is supported till the clamping lever 11 comes into action again. The lip 9<1> has a slot at the centre of less width than the normal diameter of the needle so that the body of the needle and not its point comes in contact therewith. In another form, the rotation of the magazine is obtained by mounting the pawl or a suitable catch on a curved strip adapted to slide. along the circumference of the casing under the action of the handle, and instead of a ratchetdisc the pawl may engage the needles, each in its turn, to press them towards the opening in the needle holder. A V-groove may be provided in the casing to be engaged by a needle to prevent accidental rotation, and the strip may extend along the whole circumference of the casing and have suitable apertures for the needles. In order to enable a needle jammed between the magazine disc casing to be released, the magazine disc is provided with two projections perpendicular to its plane which project through its back and normally engage any opposite two of a plurality of corresponding recesses in the face of the ratchet member, and the magazine has a springy mounting so that movement of the actuating lever will cause the disc to lift and the projections to come out of the recesses and snap into the next two holes, which movement will dislodge the jammed needle.

Abstract: 1379438 Welding by fusion BABCOCK & WILCOX Ltd 16 Feb 1972 [16 Feb 1971] 7238/72 Heading B3R A metal frame, e.g. for a diesel engine, compressor or machine tool, is made by electroslag welding together two or more curved or, as shown flat slabs 1, 2 to form a base 50 and then simultaneously or individually, electroslag welding partition members 52 to the base, the members 52 being disposed transversely of the slab joint. In welding up the base 50, the slabs 1, 2 are temporarily held together by series of welded-on braces 16, 16<SP>1</SP>, a space (E) being left between the slabs. A consumable electrode and wire guide 20, comprising strips 21-24 and filler wire guide tubes 25 welded together, is centrally held in the space (E) by longitudinally spaced insulating wedges 26. The space (E) is closed at the sides by copper dams 32, 33 to which are attached inverted U-shaped cooling water pipes 36, 37. Blocks 38, 39 are welded to the top and bottom of the slabs to extend the space (E) the bottom of which is closed by a plate 41. The space (E) is filled with flux powder, and filler wire from reels 46 is fed through the tubes 25. Welding current connections are to the electrode 20 and one of the slabs. After welding, and removal of the braces 16, 16<SP>1</SP>, dams 32, 33 and blocks 38, 39, the partition members 52 are temporarily secured to the base 50 by series of welded-on braces 51. By provision of water cooled copper dams 55, composite consumable electrodes (57), upper space extension plates 58, 61, 62 and lower closure plates 60, welding of the partition members to the base is effected in a similar manner to that for the base welding-up. Thereafter, the braces 51, dams 55, closure plate 60 and plates 58, 61, 62 and projecting weld ends are removed.

Filed: 1939-03-08
Abstract: 526,076. Engine turning-gear. BOSCH GES., R. March 8, 1939, No. 7490. Convention date, March 10, 1938. [Class 7 (v)] In vehicles having in addition to an electric power source, a source of compressed air or other non-electric power, the engagement of the pinion &c. of a starting device with the engine flywheel is effected by the non-electrical power source to bring the device into position ready for starting the engine electrically. Compressed air provided for the brake equipment of the vehicle and supplied through a pipe r past a valve q to a cylinder g displaces to the right a piston h connected through a rod i and lever e with a sleeve f on the shaft b of a starting motor a, the movement of the piston displacing the sleeve f and an associated pinion c until the pinion engages the engine to start it. When the pinion is in engagement, a bridge piece k on the rod i spans a pair of contacts n disposed or. the end of the cylinder g to complete the circuit of the battery and motor. The starting having been effected, the valve q is turned to expose the piston h to the atmosphere and a spring s returns the piston and pinion c to their inoperative positions. A number of cylinders 11, Fig. 2, may be moulded in a common assembly constituting an end cover for the motor and be arranged concentrically around the motor shaft, their pistons 13 displacing directly a plate 15 connected to the pinion 14 and having an inclined edge 18 which closes a switch 19 in a relay circuit controlling the main starting switch. In a further modification, an electromagnet opens the air valve on the stem of which the main switch is mounted, premature closure of the switch being prevented by a catch released by the piston towards the end of its movement. Prior to the release, the battery is connected to the motor through a resistance.

In the arrangement described, the relative intensity of X-rays of the desired wavelength is enhanced by the use of one or more secondary targets, employed either in the reflection or scattering mode, e.g. 34, Fig. 13, or in the transmission mode, e.g. 31, 32, 33 and 35, before it is incident upon the sample 36 under investigation, detectors 37 and 38 measuring the transmitted and characteristic radiation of the sample, when a secondary target is employed, the tube target 4 preferably has its characteristic radiation just above the absorption edge of the secondary target material, and the latter has its characteristic radiation just above the absorption edge of the element to be analysed in the sample, the target material, secondary target material, and tube operating voltage being changed for a change in the element to be analysed, for maximum efficiency. Filters may additionally be employed. Target/secondary target material pairs referred to are Mo/Cu; Pd/Mo; Pd/Pd; Pd/Pd together with a Rh absorption edge filter; and Mo/Mo together with bath on Fe transmission filter and a Zr absorption edge filter.
